Popups with data:text/html... URL can't be blocked

[rayman89]

I noticed there are many sites now that the first click you
do on the page it makes you open an other tab or pop-up. The pop-up/tab
is almost always closed immediately by ublock but is it possible to
disable that tab/pop-up from ever opening? Thanks for your time.

Example: http://animeflv.net/ or http://gorillavid.in/anq4ij0u58ug1

I'm using firefox 45 ESR x64 on W7 x64

The pop-ups and tabs that open have this format:

data:text/html;base64,PGh0bWw+PGJvZHk+PHNjcmlwdD52YXIgZXBvY2ggPSBuZXcgRGF0ZSgpLmdldFRpbWUoKTt2YXIgX2Vwb2NoRnJvbVdpbmRvd05hbWUgPSB3aW5kb3cubmFtZS5zcGxpdCgnXycpWzNdO2lmKGVwb2NoIC0gX2Vwb2NoRnJvbVdpbmRvd05hbWUgPCAyNTApe3dpbmRvdy5sb2NhdGlvbj0nJzt9PC9zY3JpcHQ+PC9ib2R5PjwvatbD4=

I tried ||data:text/html^$popup to prevent it for opening but it's the same.

I have the default options enabled with anti adblock killer, spa, malaware domains, easy privacy, easy list all the ublock filters minus experimental.

Not really. As shown in uBO's logger, a new tab with the URL about:blank, then the real URL http://animeflv.net/_a: is used, which itself redirect to firegetbook.com, which is the one filtered as a popup.

You can use the no-popups switch for that site to have the popups closed earlier, but this still won't prevent the tab from opening. Custom filter ||animeflv.net/_a:$popup will also cause the tab to be closed earlier, maybe ||animeflv.net/_a:$popup,document might be better.

Thank you.

In light of this new ABP issue, I decided to run some tests with both Firefox and Chromium to see if uBO could intercept these data: URL. Turns out, it's possible.

Thanks a lot. Do we need to add the data:text/html;base64$popup or something for it to work?

Turns out there is already such a filter in EasyList. But it doesn't work in Chromium because https://forums.lanik.us/viewtopic.php?f=62&t=32826. Until it is fixed, you may want try |data:$popup.
